To all whom may concern;

Beit Vknown that I, WILLIAM T. DICKEY, a citizen of thel United States, residing at Portsmouth, in thek county ofNorfolk and State of Virginia, have invented a new and usefuly Concrete Tie and Rail Clamp, .ofy which the following is a specification.

This invention relates to concrete ties and i clamps for securing a rail thereto.

The object of the invention is to provide a concrete tie reinforced vsoas to resist strains to which itV may be subjected and equipped with rail clamps constructed so as to preventhall possibility of chipping' of theftie `by the strain from the rails, and which permit the rail to have a slight vertical movement.

l/Vith the foregoingand other objects in view which will appear as the description proceeds,'the -inventionre'sides in the combination and arrangement of parts and in the details of ,construction hereinafter described and Claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of whaty is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a plan view of a tie constructed in accordance with this invention with two railsishown applied thereto and secured by the clamp constituting a part of the invention.

Fig. 2 is a sideelevation of the'tie with the rails shown in cross section.

Fig. 3 is an enlarged detail vertical section taken on the line 3-3 of Fig. 2.

c Fig. 4f is a plan view of one'of theclamps constituting a part of the invention, and

Fig. 5 is a longitudinal section taken on the line 5 5 of Fig. 4.- ff

In the embodiment illustrated, the tie 1 which constitutes a partl of this invention is construction of concrete, being preferably of the cross .sectional contour shown in Fig. 3. and is reinforoedby a sheet 2 of'expanded metal which extendsthe full length of the tie about one inch more or less beneath the top surface thereof. The if bars 3 and 4 extend the full length of the tie and an-l other bar 5v about four feet long is arranged between them, the three being locatedl -sides of the rails.

tion ofthe tie one inch from. the bottom, and

extending `the vfull length thereof are two reinforcing bars 6 and .7 of about tliree quarters of an inch in diameter, more or less.`

f y ce Two additional reinforced bars8 and'9 about `18 inches long arel arranged Vbeneath the rail R. Expanded metal plate 10 lis also ,Y embedded in the tie in a plane one inchl from the bottom and below the bars6," ?,'8 and 9 which extend under the rail. The longitudinal lower` edges of the tie 1 are preferablyv rounded as shown at 1'- to facilitate tarnping.

These rounded edges, Aas shown at 1a., `also ,i act as a brace to hold the tie in; an upright.,

position. The tie l1 is provided acent the Y thereof'in itscopposite side l edges with recesses 11v to 'facilitate theapplication ofthe nuts 12iwhich are-engaged with the lower ends of the bolts 13. Arllhese'bolts are pro-, vided atV their Aupper 'ends with nuts', 135 l whichsecure the-.rail clamping plates 15, a' coiled spring 111 being arrangedbetweenfthe if nuts 13"l andsaid'plates;vk The` nutsonthe lower endsof the bolts ,c'orrode after they have been in use'someti'Ine-and aredifficult to remove. The nuts on the upper. ends may easily be taken oif and permit the clamps to be removed in a few seconds.` The clampingr plates` 15 are each constructed as shown in detail in Figs. i-and 5,

being mounted for vertical movement on the bolts 13 which pass through longitudinally extending slots 16 in the fasteners or plates. Each of these clamping plates includes a finger 17 which overhangs andengages the base flange of the raill R. Eachof the fas' teners 15 is provided with a longitudinal Y slot 16 and the remote ends of the fasteners are extended at vright angles asis shown'at" 18, being designed to enter sockets 19 formed in the upper faces of the tie 1 on opposite the clamp a're beveled on their louter faces and result in distributing the strain orpres-l sure of the clamp vertically downward and The toes or ends18 of looy at the body of the tie' at an angle instead l of exerting a straight .back push and thus` ward shock from. the wave motion of theii rail, but they also act as nut locks for the .1i

nuts on thebolts, y 'n sof' rlhe rails R are preferably mounted onl cushioning plates 22 and are held engaged therewith by the clamps l5. These clamps 15 may be moved toward and away from each other owing to the formation of the slots 16 therein, the object of this being to permit the clamps to be shifted to provide for the adjustment of the rail and proper mounting of the clamps.

The tie l herein disclosed is practically indestructible land the cost thereof is nominal probably not exceeding that of a first class wooden tie, while its life greatly exceeds that of such a tie.

The fasteners l5 are so constructed and mounted thatv they will grip and hold the rail and yet permit ai slight vertical movement thereof. lt will also be observed that the bolts and fasteners can be inserted and removed without disturbing the position of the tie in the ballast or jacking up the track. If the 'rail' wears down in the tie, the faseners .l5 will follow the rail and holdit securely owing to the presencefof the springs 14. It is ofcourse understood that the fasteners l5 may be applied to any kind of a.

longitudinally extendingbolt"v receiving; slot thereiny with a rail engaging finger at one end and a tie engaging toe at the other, said toe extendingv atV right; angles to the body.'

f lique angle on the tie, and. springs on said bolts abovexsald clamps. and anadjustable.

member on the bolt and cooperating with the spring.

1l. A cement. railroad tie having bolt re'- ceiving openings therein and socketswadjacent said openings, boltsmounted in 'said openings, rail clamps mountedo'n saidbolts', and' having; toes to enter said. sockets, said toes being beveled'y on their outer facesfat their terminals to exert' pressure at'fan oblique angle-on the tie, sprin'gson` said bolts above saidclamps and cooperatingwiththey spring, said. bolts having kremovable nuts on their opposite'ends.

Intestimony that I claim the foregoing as y my own, I have hereto atliiredl my signature in lthe presence of two. witnesses. n
